I order 90% of my feeders from
http://www.mulberryfarms.com/
yes the shipping on standard overnight is not cheap and can be almost as high as the cost of the bugs.
but to cut down costs, I order the following...
25 butterworms...they keep in the fridge for at least two months.
a cup of hornworms...ask for small ones, and slowly feed them off. keep in the fridge every other day to slow their growth. you'll toss out half of them, but they make a great feeder.
50 small superworms...some will be large enough to use right away, the rest you can grow up untill ready.
100 small silkworms...they will come way too small to use right away. so start feeding the hornworms, then the supers that are ready, then the butters, then your silkworms will be ready to start feeding.
buy a cup or two of 100 crickets to add in to the mix and you wont pay any extra for the shipping.
just remember to buy smaller then you'll need as you will only be feeding crickets every other day or so, and they will grow almost as fast as your silkies and hornworms.
total price should be around $100 with overnight shipping, but that's for a months worth of food for your cham...maybe even more.
